THANH HOA—Vietnam’s Con Moong Cave, located in Cuc Phuong National Park, sheltered prehistoric people for more than 10,000 years. Archaeologists have found thousands artifacts left behind by hunter gatherers and early farmers in the cave since excavations began in 1976. Recent digs have uncovered the remains of four Paleolithic people who had been buried with their stone tools. The cave could qualify for UNESCO World Heritage status.
